PCT No. PCT/SU89/00105 Sec. 371 Date Jan. 23, 1990 Sec. 102(e) Date Jan. 23, 1990 PCT Filed Apr. 20, 1989 PCT Pub. No. WO89/11414 PCT Pub. Date Nov. 30, 1989.A high-speed craft comprises a hull (1), lifting wings (2) with sponsons (3), and a tail fin assembly including a vertical keel (5) and a stabilizer (6) having an inverted-V configuration and rotatably mounted about a vertical axis (7), driven by a steering gear (13,15). In turning the craft, the forces acting on half-wings of the stabilizer (6) generate a moment making the craft heel to the inner side of the bend, whereby the transverse component of the aerodynamic lift opposes to the lateral drift caused by centrifugal forces acting on the craft.
